STEM ARBOR WHEEL AND RATCHET.

EBPECIPICATION forming part of Letters Patent No. 328,307, dated October13, 1885,

Application filed July 8, 1885.

To all whom it may concern.-

Be it known that I, GEO. E. HART, of Waterbury, in the county of NewHaven, and in the State of Connecticut, have invented certain new anduseful Improvements in a Combined Winding Pinion and Ratchet; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which- I Figure 1 is a perspective view of the blank used for mywinding pinion or wheel. Fig. 2 is a like view of the same aftercompletion. Figs. 3 and 4 are respectively perspective views of theratchet and hub blank and of the completed ratchet and hub. Fig. 5 is alike view from the outer or front side of said pinion and ratchetcombined, and Fig. 6 is a central section of the same upon an axialline.

Letters of like name and kind indicate similar parts in each of thefigures.

My invention has for its object the ready production of a wheel orpinion having ratchet or other teeth sunk below the plane of its face,to which end said invention consists in a wheel or pinion constructed inthe manner and for the purpose substantially as hereinafter shown.

In carrying my invention into practice a disk of metal, A, having asuitable diameter and thickness, is provided with a central opening, a,that equals or is slightly larger in diameter than the ratchet, and hasout within its periphery gear-teeth a, of usual form and number.

A second considerably thicker disk, B, is placed between suitable diesand subjected to pressure until its faces are caused to conform thereto,and its front face is provided with a concentric row of ratchet-teeth,b, and its rear face has the hub shape shown in Figs. 4 and Serial No.171,004.

(No model.)

6. By the same or by any usual means the periphery of saidratchet-section is provided with a rabbet, b, which corresponds indiameter and depth to the diameter of the opening a and the thickness ofthe wheel or pinionsection A, and enables said ratchetsection to beinserted within said opening. when said parts will present theappearance shown in Figs. 5 and 6, said ratchet'teeth being flush withor slightly below the front face of said pinion-section. If desired,said section B may be given its form by any other means than dies. Anaxial opening, b is now, or, if desired, at any previous stage, providedwithin the ratchet-section B, after which the parts thus constructed arepermanently secured together by any usual means-such as a close-pressedfit, dowel-pins, screws, solder, &c.-when the combined pinion andratchet presents precisely the same appearance, and is for allpracticable purposes the same, as though made from one piece, while morereadily constructed and more perfect in construction than would bepracticable by means heretofore employed.

Having thus fully set forth the nature and merits of my invention, whatI claim is The pinionsection A, consisting of a fiat peripherallytoothed ring, in combination with the ratchet-section B, having withinone end a ring of ratchet-teeth, 1), within its periphery the rabbet b,and at its axis the opening 6 substantially as and for the purposeshown.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of June, A. D. 1885.

GEORGE E. HART.
